The Hot Air Company™

Turning server heat into sustainable energy.
We recover data centres’ excess heat to power thermal-intensive processes – from urban farming to bioprocessing – unlocking new revenue, slashing operational costs, and driving circular innovation across industries.  

At The Hot Air Company, we believe cities can be more than just consumers of energy - they can become regenerative ecosystems of opportunity. Every day, data centres expel vast amounts of wasted heat, while biomanufacturers face soaring operational costs and energy barriers. Our solution is simple but transformative: we capture this excess heat and redirect it to power high-growth, sustainable industries like alternative proteins, bio-manufacturing, and circular agriculture. By connecting two major challenges - energy waste and the rising demands of new bio-industries - we create a closed loop system where sustainability drives profitability.  

We believe the future won't wait. As demand for cloud computing, biotechnology, and clean energy skyrockets, the systems that power our lives must evolve - fast. The Hot Air Company was founded to meet this pivotal moment: when the choice is not longer whether to act, but how smartly and bodly we act. Our work is driven by urgency, optimism, and the conviction that solving the energy-waste problem is key to unlocking a truly sustainable economy.
